Answer:
Answer to the following question is as follow.
Explanation:
Civil engineering industrial development projects have a significant influence on the environment, particularly in terms of excessive noise, environmental pollution, and land shrinkage.
Engineers have totally transformed our environment, from contemporary dwellings to bridges, space flight, automobiles, and cutting-edge mobile technologies. Engineers utilise their expertise to build new and exciting prospects and address any difficulties that may occur, and they employ their innovative ideas to accomplish so.
Power tools are usually run on one of the three types of power: Compressed air, electricity, or combustion
Answer:
The crash rate is 22 vehicles per 1 million vehicles
Explanation:
In this question, we are asked to determine the crash rate per million vehicles.
Crash rate is calculated using average crash frequency.
The crash rates are calculated based on the number of crashes per million vehicle miles travelled in a year.
Mathematically;
crash rate = (48 * 1,000,000)/ [(980 + 1560 + 1230 + 900 + 1435)* 365]
= 48,000,000/(6105*365)
= 21.54 approximately 22
There should be a 6" free conductor left for splicing
Why there should be 6" splicing?
You must leave the junction box with at least six inches of free conductor wiring when running electrical cables from the box to the box for connecting needs.
Actually, 6-8 inches can be left when running the electric cables, additionally even if the grounded conductor is to be spliced in a 12-inch by 12-inch.
Conductor splicing: A splice, which can be finished using either the crimping or soldering method, is the joining of two or more conductors in a way that produces a permanent electrical termination and mechanical link.
Hence we can conclude that 6 inches is fine for the conductor splicing
